Abstract
A filter having an impulse response including a first partial impulse response and a second partial impulse response includes a supplementary filter having a supplementary impulse response. A first filter has the first partial impulse response using an output of the supplementary filter as an input and a second filter has the second partial impulse response using an output of the supplementary filter as an input.
Claims21
A filter having an impulse response of a function that comprises a first partial impulse response and a second partial impulse response, comprising:
- a supplementary filter, comprising a digital processing circuitry including at least one output node for an output of the supplementary filter, configured to generate a supplementary impulse response via the digital processing circuitry at the at least one output node;
- a first filter, comprising an additional digital processing circuitry including at least one input node coupled to the supplementary filter, configured to generate, by the additional digital processing circuitry, the first partial impulse response using the output at the at least one output node of the supplementary filter and at least one additional input at the at least one input node as inputs of the first filter;
- and
- a second filter, comprising a further digital processing circuitry including at least one additional input node coupled to the supplementary filter, configured to generate, by the further digital processing circuitry, the second partial impulse response using the output at the at least one output node of the supplementary filter and the at least one additional input at the at least one additional input node as inputs of the second filter;
- wherein the digital processing circuitries comprise at least a multiplier, a delay element, and an adder;
- and
- wherein the supplementary filter, the first filter and the second filter combine to provide the impulse response.
